Consolidating adjacent titles is not an administrative shortcut that suits every property. The titles must be checked for compatible ownership, estates, mortgages, easements, covenants and other interests, and the proposed outcome may require planning, cadastral surveying, lender consent and legal work before a new title can issue.
If you own two or more adjacent properties — perhaps a house and the section next door, or a series of small lots you've acquired over time — you may be paying separate rates, managing multiple titles, and dealing with unnecessary complexity. Title consolidation (also called amalgamation) lets you merge those titles into one, simplifying ownership and reducing ongoing costs. This guide covers when consolidation makes sense, the legal process, and what you need to know before you start.
What Is Title Consolidation?
Title consolidation is the legal process of merging two or more separate titles into a single title under the Land Transfer Act 2017. Instead of holding three certificates for three adjacent sections, you hold one certificate covering the combined area.
This is different from subdivision (which splits one title into many) — consolidation goes in the opposite direction. And it's different from boundary adjustment, which shifts borders between titles without changing the number of titles.
When Does Consolidation Make Sense?
1. You Own Adjacent Properties and Want Simpler Administration
Multiple titles mean multiple rates bills, multiple title references on legal documents, and multiple records to keep track of. Consolidating into one title reduces this administrative overhead.
2. You're Developing Land and Want a Clean Starting Point
Developers often consolidate multiple small titles before re-subdividing into a new layout that makes better use of the land. It's easier to work from one title than from several.
3. You've Inherited or Purchased Multiple Adjoining Lots
Family land is often held in multiple small titles. Consolidating them creates a single, more marketable asset.
4. You Want to Remove Redundant Boundaries
Old subdivisions sometimes created lots with boundaries that no longer serve any purpose — for example, a fence line that divides your front and back yard across two titles.
5. Lender or Council Requirements
Some banks prefer a single title when lending against multiple adjacent properties. Councils may also require consolidation as a condition of resource consent for certain developments.
When Consolidation Might NOT Be the Right Move
- Different zoning or restrictions: If one title has specific covenants, easements, or conditions that don't apply to the other, merging may complicate or dilute those protections.
- Separate financing: If each title has its own mortgage with different lenders or terms, consolidation may require refinancing.
- Future sale plans: If you intend to sell one lot separately in the future, consolidation removes that option — you'd need to subdivide again, which is costly.
- Tax implications: Talk to your accountant. Merging titles can have GST or tax consequences depending on your circumstances.
The Legal Requirements for Consolidation
Titles Must Be Adjoining
You can only consolidate titles for land that shares a common boundary. Non-adjacent properties cannot be merged into one title.
All Titles Must Have the Same Owner(s)
Every title to be consolidated must be registered in the same ownership. If titles are in different names (even different permutations of the same owners), you'll need to transfer them into identical ownership first.
No Conflicting Interests
Existing mortgages, easements, covenants, and other registered interests must be compatible. If one title has a restrictive covenant and the other doesn't, merging them may require consent from the benefiting party or the removal of the covenant.
Council Approval
You'll typically need a certificate from the local territorial authority under section 221(3) of the Resource Management Act 1991 (or the relevant provision of the Land Transfer Act 2017) confirming that no conditions prevent the amalgamation.
Survey Plan Requirement
In most cases, a licensed surveyor must prepare a consolidation survey plan showing the merged boundaries. This plan is deposited with the titles office as part of the registration process.
Step-by-Step: How to Consolidate Titles
Step 1: Obtain Current Title Information
Order a Record of Title with Diagram for each title you intend to consolidate. This shows you the current boundaries, ownership, and any registered interests.
If the titles are complex — with multiple easements, covenants, or mortgages — consider the Pre-Purchase Package for the most comprehensive view.
Step 2: Engage a Licensed Surveyor
A cadastral surveyor will prepare the consolidation plan. This involves:
- Surveying the combined boundary
- Preparing a deposited plan (DP) that defines the new shape
- Ensuring the plan complies with Surveyor-General's rules
Step 3: Obtain Council Consent
Apply to the local council for a section 221 certificate (or equivalent). The council will check that:
- No resource consent conditions prevent amalgamation
- Any existing consent notices can be satisfied
- The proposed consolidation doesn't create planning issues
Step 4: Deal with Existing Interests
If the titles have mortgages, your bank will need to consent to the consolidation and may require the mortgages to be restructured. Easements and covenants that cross the internal boundaries being removed will need to be dealt with — either discharged, modified, or converted into internal arrangements.
Step 5: Lodge with the Land Registration System
Your solicitor lodges the consolidation dealing through the electronic land title register, including:
- The consolidation plan
- Council certificate
- Discharge of redundant mortgages or easements (if applicable)
- Transfer instruments to merge the titles
Step 6: Registration
Once processed and approved, the individual titles are cancelled and a new consolidated title is issued. The new title will carry forward any surviving interests (mortgages, easements, covenants).

Common Pitfalls
Mismatched Ownership
The most common delay. If Title A is owned by "John Smith" and Title B is owned by "John David Smith," they need to be transferred into identical ownership before consolidation can proceed.
Forgotten Easements
That right-of-way across your neighbour's property? If it's on one title but not the other, consolidation may inadvertently remove it — or make it internal and unenforceable. Always check for easements on your title.
Mortgage Consent Delays
Banks don't always move quickly. Apply for mortgage consent early in the process.
Council Conditions
Some councils impose conditions on consolidation — such as requiring amalgamation conditions that prevent future re-subdivision. Read these carefully.
Alternatives to Formal Consolidation
If formal consolidation seems like overkill, consider:
- Amalgamation condition: Instead of consolidating, a condition on the titles requires them to be held together and not sold separately. Simpler, cheaper, but the titles remain separate.
- Boundary adjustment: If you just want to shift a fence line, a boundary adjustment may be cheaper and simpler than full consolidation.
- Cross-title easements: If the issue is access between the lots, registering easements may solve the problem without consolidation.
How Title Searches Support the Process
Accurate title information is essential before, during, and after consolidation:
- Before: Record of Title with Diagram for each title shows boundaries, ownership, and interests
- During: A Guaranteed Search provides official confirmation of the title state at a specific date
- After: Order a new Record of Title to confirm the consolidated title is correct

Practical process
- Obtain the current records, instruments and relevant plans for every title proposed for consolidation.
- Compare ownership, tenure, mortgages, covenants, easements, notices and legal descriptions across the titles.
- Ask a property lawyer and licensed cadastral surveyor to confirm the feasible process, approvals, consents and final title outcome.
Decision guide
| Situation | Next step |
|---|---|
| All titles have the same owners and compatible interests | Seek a professional feasibility check before assuming the consolidation is straightforward. |
| Ownership, mortgages or registered interests differ | Resolve the mismatch and obtain affected-party or lender advice before survey and registration work. |
| Future subdivision or separate sale is possible | Model the loss of separate-title flexibility before choosing consolidation. |
Common mistakes and risks
- Assuming adjacency alone makes titles eligible to be merged.
- Ignoring different mortgages, estates or registered interests across the parcels.
- Consolidating without considering future finance, subdivision or separate-sale options.
Key takeaways
- Feasibility begins with every current record and supporting document.
- Planning, survey, lender and legal constraints can all affect the outcome.
- Compare the long-term benefits with the flexibility lost when separate titles disappear.

Frequently Asked Questions
Can I consolidate titles with different owners?
No. All titles must be held in identical ownership before consolidation can proceed. If ownership differs even slightly (different middle names, different trust structures), you'll need to transfer the titles into the same ownership first.
How long does title consolidation take?
Will consolidation affect my rates?
Generally yes — you'll go from multiple rates bills to one. The total rates may be similar or slightly different depending on how the council revalues the consolidated property. Check with your local council for specifics.
